我想实现它在安卓你好定义的视图例子的MapView的例子，但现在我面临着这样的错误：

I'm trying to implement the MapView example which is defined in Android Hello Views example but now I'm facing this error:

Failed to find provider info for com.google.settings

任何想法，为什么会这样？

Any idea why this is happening?

推荐答案

的MapView例如不设置为默认的API密钥。所以，你必须将它。下面是一步一步：

The MapView example doesn't set API key by default. So you must set it. Here is step by step:

从系统中获取MD5

Get MD5 from your system

%JAVA_HOME%\bin\keytool.exe -list -alias androiddebugkey -keystore "%userprofile%\.android\debug.keystore" -storepass android -keypass android

获取API密钥通过粘贴生成MD5此页： http://$c$c.google.com/android/maps-api-signup.html

Get API key by pasting the generated MD5 to this page: http://code.google.com/android/maps-api-signup.html

粘贴生成的API密钥为 {} your_project_root /res/layout/map.xml

Paste the generated API key to {your_project_root}/res/layout/map.xml

<com.google.android.maps.MapView
    android:id="@+id/myMapView"
    android:layout_width="fill_parent" 
    android:layout_height="fill_parent"
    android:enabled="true"
    android:clickable="true"
    android:apiKey="paste_generated_api_key_here"
/>

在 AndroidManifest.xml中，请确保您有如下因素标记到你的应用程序标签：

In AndroidManifest.xml, make sure that you have the folowing tag into your application tag:

<uses-library android:name="com.google.android.maps" />

也是如下因素标记到你的清单标签：

<uses-permission android:name="android.permission.INTERNET" />

刷新项目和运行

Refresh your project and run
